How can I make my enable or disable dropdown box work for my custom extension? - magento-1.9

Question

I have made a query extension where you can ask your query, and then get a reply from admin. And I have already managed to get the extension setting tab added as a tab in the admin configuration area, and created "Product Query" menu also.
successfully created this tab

Please guide me, where I should write those code,by this i can disable or enable this extension with this disable/enable dropdown.

Answer 1

I solved the issue.May be someone will be helpfull by this answer. That's why I update my answer.
So,at first write this anywhere to check it is working or not
$enableorDisable = Mage::getStoreConfig('productquery/settings/enable',Mage::app()->getStore());
print_r($enableorDisable); die();
if answer is 0 when your module is disable and answer is 1, when your module is enable. then it is working fine.. And you have to add following line in your block.
<action method="setTitle" translate="value" ifconfig="productquery/settings/enable"><value>Product Query</value></action>
add ifconfig="modulename/group name/field name"
Thank You..
